87223207 divided by 949 
The aim is to understand the frequency of 949 in 87223207.

Let's proceed to step 1:
When dividing 8 by 949, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 949

Going ahead to step 2:
When dividing 87 by 949, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 949

Moving on to step 3:
872 divided by 949 is 0 with a remainder of 872.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 872 and we're left with 872.
Include the next digit (2) from the dividend after 872, then repeat: 8722 / 949

Going ahead to step 4:
949 can be fit into 8722 9 times, resulting in a remainder of 181.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 8541 from 8722 leaves us with 181.
Bring next digit (3) of the dividend behind the 181 and repeat the process: 1813 / 949

Step 5:
When dividing 1813 by 949, we get 1 with a remainder of 864.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we subtract 949 from 1813, we get 864.
Include the next digit (2) from the dividend after 864, then repeat: 8642 / 949

Advancing to step 6:
949 goes into 8642 9 times with a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 919.0
Subtracting 8541 from 8642 leaves us with 101.
Bring next digit (0) of the dividend behind the 101 and repeat the process: 1010 / 949

Step 7:
If we divide 1010 by 949, we get 1 and a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 9191.0
Deduct 949 from 1010 and we're left with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 949

On to step 8:
949 can be fit into 617 0 times, resulting in a remainder of 617.
Put 0 as the next digit of the answer. 
Result so far: 91910.0
If we subtract 0 from 617, we get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Step 9:
The number 949 fits into 6170 6 times, leaving a remainder of 476.
The number 6 becomes the next digit in our result. 
Result so far: 91910.6
If we subtract 5694 from 6170, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 10:
4760 divided by 949 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 91910.65
The remainder is 15 after subtracting 4745 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
If we divide 150 by 949, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 91910.65
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
949 goes into 1500 1 times with a remainder of 551.
Record the quotient 1 as the next digit in the result. 
Result so far: 91910.6501
The remainder is 551 after subtracting 949 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 13:
949 can be fit into 5510 5 times, resulting in a remainder of 765.
Record the quotient 5 as the next digit in the result. 
Result so far: 91910.65015
Subtract 4745 from 5510 to get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

On to step 14:
The number 949 fits into 7650 8 times, leaving a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 91910.650158
Subtract 7592 from 7650 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
580 divided by 949 is 0 with a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 91910.650158
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 16:
949 can be fit into 5800 6 times, resulting in a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 91910.65015806
If we take 5694 away from 5800, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 91910.65015806 with a remaining 1.06e-07.
